6 Claims.

This invention relates to a non-clogging coal crusher which by its unique structure will prevent the crushers rolls from being clogged should a harder substance than coal be deposited there- An object of this invention is to provide a coal crusher that will automatically operate to permit substance of foreign material to pass there through without clogging the crushers rolls thereof.

Another object of the invention is to provide a coal crusher that is efficient in operation, durable in use and by its unique structure permits easy removal or repairs of the crusher rolls.

With the above and other objects in view the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of an embodiment of the invention;

Figure 2 is a top plan View thereof;

Figure 3 is a rear view thereof;

Figure 4 is a sectional View on the line 4 4 of Figure 3;

Figure 5 is a sectional view on the line 5 5 of Figure 3 Figure 6 is a sectional view on the line 6-6 of Figure 4 Figure '7 is a detailed fragmentary view of the bearing slot for the power crusher;

Figure 8 is a front end view of the bearing for the power crusher;

Figure 9 is an interior side view thereof;

Figure 10 is a rear end view thereof;

Figure 1l is a sectional view on the line Il of Figure 9;

Figure 12 is a perspective view of a rubber cushioning member.

Figure 13 is a modification of the invention and Figure 14 is a sectional view on the line |4'-|4 of Figure 13.

Referring more in detail to the drawing the reference numeral 2G designates the frame or body of the coal crusher having the side walls 22, supporting legs 24 having iianged supporting feet 215 on the lower end thereof and the sides are joined by the fixed front end wall section 28 having the marginal flange 38 secured to the outer marginal side edge of the side walls 22 and rear end wall 32 having the depending portion 34 engaging the rear edges of the front legs 24 and the forwardly directed semi-circular projections 36 formed at the upper edge of the rear end wall and relatively spaced from each other for a purpose to be later described.

Secured to the wall 32 in vertical relation thereto and to the feet 25 at the lower end thereof are the outer upright guide members 38 which are provided at their upper ends with horizontal right angled outwardly extending flanges 39. Secured to the wall 32 intermediately of the members 38 are the inner guide members 40 which are relatively spaced from each other and the members 38 and bridged at their upper ends by the cross member 442.

The sidewalls 22 are bridged at their upper ends by the transverse bar 44 and engaging this bar at its upper end and the wall section 28 at its lower end is the removable section 46 of the front end wall which is secured to the side walls 22 by fasteners 48. This wall is curved as shown to con1 form to the shape of the side walls 22.

Adjacent the upper end of the front legs 24 and the side walls 22 there are formed inclined open ended slots 5i] having a Straight upper edge 52 curved bottom edge 54 and rounded bottom 56. These slots are formed to mount the transverse shaft 58 to which is secured the crusher roll 6i) and it is to this shaft that power is applied from a power source not shown.

The section 46 is provided so that this roll can be removed as desired for repair or the renewal thereof.

Removably mounted in the slots are the bearing members 62, having the bearing opening 64 for the shaft 58 and apertures 66 for receiving fasteners to secure the members to the side walls. The members 62 are inclined at their forward end at 68 and rounded at their rear end at 1i). The inwardly directed reduced portion 12 is received in the slots 50 and is chamfer-ed at its rear to conform to the shaft 58. The portion l2 is provided with the substantial by triangular shaped depending projection 14 to close the slot 53 and the projection at its forward end is bevelled at ."6 and it will be seen that when the members 62 are in position and secured by fasteners 'i8 the projection 14 engages curved bottom edge 54 of the slot 50 and the forward edge 68 conforms to the forward edge of the sidewalls and the members 62 is provided with an offset 82.

The upper edge and downwardly curved rear edge and lower straight edge of the side -walls are provided lwith conforming flanges ySi. and bearing anges 84 in which are journalled the transverse shaft 86 of the roller adjuster frame 8-8 Iand removable upper bearing plates Sii secured to the side walls by fasteners 92 conform to the shape of the side walls and the flanges thereon.

The roller adjusting frame 88 is loosely mounted on the shaft 86 and comprises arcuate side members 94 having cutouts 95 in the convex inner edg'e thereof which are bridged at their upper end by the substantially curved cross member 96 and at their bottom by the substantially curved cross member 88 and on the concave side of the members 94 are provided removable bearing plates |00 which are secured to the members 94 by fasteners |02 and serve to journal the relatively spaced axles I @d Vof the Crusher rolls |06, which are in parallel relation to each other and confront the crushing roll 60 and also permits removal of the rolls as desired. The member 98 is provided with spaced recesses |08 to receive the apertured tongues IIO of the arcuate shaped arms I I2 and thus the arms are connected to the shaft 86.

The arms are slotted at their lower ends at I I4 to receive the tension rods IIS which are connected at their opposite apertured ends to the lower ends of the members 911 by pivot bolts I I8 and a :spring |20 on .the rods IIB engaging a shoulder |22 thereof, at one end and the arms at the other ends tension the arms II2 by means of manipulation of the nuts |24 on the forward threaded end of the rods I I6.

The arms II2 are joined by the curved partition |26 and have forwardly extending projections |28 formed thereon which extend forwardly of the arms to be received between the outer and inner guide members 38 and 0 respectively.

Secured to flanges 39 of the members 38 and the cross members 62 by fasteners |30 is the transverse member |32 having blocks |34 on the undersurface thereof to be seated between the members 38 and d0 and semicircular forwardly extending apertured projections |36 which are in alignment with the projections 36.

Positioned intermediate the members 3S and crushing of the coal between this roll and the crushing rolls |08. Manipulation of the members |38 or the screws |50 determine the size of the coal as it passes through the crusher to be discharged at the bottom thereof.

Thus a Crusher has been provided that due to its unique structure will not clog and will crush coal into various sizes.

It is believed that the operation and construction of the Crusher will Ibe apparent to those skilled in the art and it is to be understood that changes in the details of construction, arrangement and combination of parts may be resorted to .provided they fall within the spirit of the invention and the scope of the appended claims.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. In a coal crusherhaving a frame having side walls and supporting feet therefor the improvement comprising a crusher roll mounted in said frame transversely thereof, a Crusher roller ad.- justing frame mounted in said rst frame, a yplurality of crusher rolls positioned in said crusher roller adjusting frame and transversely thereof and confronting said rst crusher roll, means for tensioning said .Crusher roller adjusting frame connected to the lower ends thereof, a shaft supported by said side walls for pivotally mounting the upper end of said Crusher roller adjusting frame thereon, arcuate shaped arms receivable at their upper vend on said shaft and extending from said shaft outwardly of the Crusher rolls in said Crusher roller adjusting,r frame, a .projection on said arms at right angles thereto and outwardly thereof, cushioning means for said arms engaging said projection and sides and means l' n': l I

6. The invention as in claim 2 wherein the operating means engaging said projection comprises a plurality of cushioning means positioned on opposite sides of said projection and means passing through said projections and said cushioning means for retaining the same in position.
